Parasitic Battery Drain - AVIC 8200 NEX

Recommended Posts

Does anyone know how many amps the 8200 unit drains from the battery when vehicle is off?

 

I recently bought a used vehicle and shortly there after upgraded the head to an 8200 NEX. I also installed a new battery.  

 

After sitting for a few days, the battery is too weak to start the car.  With all car components off, there is a .176 A drain on the battery which seems high.  When I pull the radio fuse, the drain drops to .016 A.  I appreciate if anyone can share what the expected range of the parasitic drain is for the 8200.

 

<I think it is a great head unit by the way>

All modern radios have some battery drain to maintain basic functions such as the clock, radio pre-sets and other functions when the vehicle is off.  A parasitic drain of .05 A or less is considered typical.

 

To make it clear, no, I did not wire directly to the fuse box.  I followed recommended wiring instructions and used wiring harnesses from Crutchfield.

 

After performing a parasitic diagnostic, I found that something behind the fuse for the radio is pulling .176 A drain when the vehicle is off which is a little over 3 times what is considered normal.

 

I bought the vehicle used, so I don't know if there was something else modified before I purchased.  I will be consulting the wiring diagram and further troubleshooting next weekend.

 

If anyone knows of the amperage from their head unit (8200) when the vehicle is off, I would find that very useful.

 

Thanks!

A disclaimer: I know nothing about a 8200, so I can't help much. But I was wondering if you leave anything plugged-in to the USB (an iPod maybe) that could consume power even if the ignition is off.

I’ve found that some vehicles have constant power to the power outlets all the time. So as for RonS said my 2008 Chevy and 2007 Pontiac’s power outlets were always on even with key off. My 2010 Dodge has a keyed power outlet. I E the outlet has no power with the key off. It’s makes a difference what make vehicle you have.
